Alzheimer's disease (AD) is a common neurodegenerative disease that is characterized by the abnormal accumulation of intracellular and extracellular amyloid-β (Aβ) as well as disruption of the blood brain barrier (BBB). Fibrinogen plays an essential role in regulating thrombosis, wound healing, and other biological functions. In the present study, we investigated the relationship between three polypeptide chains α, β, and γ (FGA, FGB, and FGG) and Aβ deposition in the APP23 plus chronic cerebral hypoperfusion (CCH) mice model as well as the human AD brain. FGA, FGB, and FGG accumulated when Aβ was deposited in neural cells and cerebral vessels. This deposition was significantly higher in AD plus CCH mice models relative to wild-type brains, and in human AD brains compared to control brains. The present study demonstrates that FGA, FGB, and FGG are associated with AD progress, and can thus be potential targets for the diagnosis and therapy of AD.
